This program easily and conveniently converts cubic-feet-second to acre-feet per year and vice versa. To operate, enter the number you wish to convert in either manually entry box. The conversion appears in "teal" in the opposite box.

Press the "Return" button to return to the calculator.

Occasionally the message "NaN" is observed in one of the computational fields. This is an error message which stands for "Not a Number" and is generated because something other than a number has been entered in one of the manual entry fields. NaN's must be corrected before numerical results will be displayed.
